If you don’t spend a lot of time in parks then you probably don’t often think about the rangers who maintain and protect parks and other natural environments all around the world. Rangers are the people whose job is to protect the world’s wilderness through education and action. In some parts of the world, this is an especially dangerous job. Rangers not only have to be prepared to deal with natural disasters such as floods and fires, but they also have to fight against people who aim to harm the natural landscape such as poachers and other criminals. World Ranger Day is a holiday to recognize people who do this job and to remember those who have lost their lives.
